[ovs-discuss] Running userspace as nonroot

[Aaron Rosen]

Thanks Ben,

I'm trying to use ovs without the kernel module. When I start ovs-vswitch
I'm getting the following error. Any idea whats going wrong? Sorry for all
the questions.


arosen at ubuntu:~$ ovs-vsctl --no-wait
--db=unix:/home/arosen/usr/local/var/run/openvswitch/db.sock init
arosen at ubuntu:~$ ovs-vswitchd
unix:/home/arosen/usr/local/var/run/openvswitch/db.sock --pidfile --detach

Thanks,
